Modified Bond Ball Mill Work Index Test

The Thirty-nine samples were submitted for the Crusher Index (Ci), SAG Power Index (SPI®), Standard Bond Ball Mill Work Index (BWI) and Modified Bond Ball Mill work Index (MBI) tests. The Ci, SPI® and Bond Wi values of these samples show a good indication of ore hardness variability within the ore body.

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is by, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.

SIPI (Structure Insensitive Pigment Index)

The SIPI index maximizes sensitivity to the bulk carotenoids to chlorophyll ratio, while minimizing the impact of the variable canopy structure. It is very useful in areas with high variability in the canopy structure, or leaf area index.. Values description: SIPI values range from 0 to 2, where healthy green vegetation ranges from 0.8 to 1.8.

How do database indexes work?

Indexes speed up your read queries. Indexes are basically a way to speed up your read queries, particularly ones with filters ( WHERE) on them. They're data structures that exist in your database engine, outside of whatever table they work with, that point to data you're trying to query. To avoid the all-too-common librarian metaphor ...

Wire Bond / Ball Shear Application Note

Figure 1. Ball bonding steps. At the beginning of the wire cycle, the bonding tool travels down to the first bond location (Steps 1 and 2). The first bond is achieved by bonding a spherical ball to the pad using thermal and ultrasonic energy (Step 3). The initial bond is also referred to as the ball bond.

How to use IndexedDB to Store Local Data for your Web App

The simplest method is to delete an entry directly by its known key: const deleteCar = store.delete(1); deleteCar.onsuccess = function () { console.log("Red Toyota has been removed"); }; If you don't know the key and want to remove based on the value of one of your indexes, you can do that too:

BOND'S WORK INDEX: WHAT IT IS AND WHAT IT ISN'T

The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of –0.45 in the 100 µm to 200 µm size range, not the –0.50 exponent empirically measured by F. Bond. The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energy
